Condensation between panes in Bankers Hill, San Diego
Condensation or fog that forms between the two panes of glass, not on the interior or exterior surface, is a sign the insulated glass unit's seal has failed. This is different from ordinary condensation on the room-side surface of a window, which is a humidity issue, not a broken seal.
1900s-1930s stock, custom sizing and noise reduction.This is dense, older housing on small lots close to I-5, I-8, and busy arterial corridors, so street noise is as much a driver as temperature. Many original wood-sash windows from the 1900s-1930s are still in service, painted shut or warped out of square, alongside the single-pane aluminum that replaced some of them mid-century.
The mansion blocks off Fifth and Sixth near the park hold larger, older openings where owners often want a wood-clad or wood-look replacement that preserves the historic street presence rather than a plain vinyl swap. The high-rise towers around Laurel and Nutmeg pick up real salt air off the bay, which corrodes exposed hardware on lower and mid-level units faster than the interior mesa.
What causes it
- Failed IGU seal letting humid air into the sealed cavity between panes
- Loss of the argon or krypton gas fill through the same seal failure
- Age: most IGU seals reach the end of their service life somewhere between 10 and 20 years
How it gets fixed
- IGU glass replacement when the frame and sash are sound
- Full window replacement when the frame is also compromised

Condensation between panes questions in Bankers Hill
Why does this happen in Bankers Hill?
Condensation or fog that forms between the two panes of glass, not on the interior or exterior surface, is a sign the insulated glass unit's seal has failed. This is different from ordinary condensation on the room-side surface of a window, which is a humidity issue, not a broken seal.. In Bankers Hill, the estate homes often keep historic wood window profiles through careful full-frame replacement or restoration-grade retrofit, while the high-rise towers run large fixed and sliding units that need specialty high-rise installation logistics when they fail., which shapes how this shows up.
What is the difference between condensation on the glass and condensation between the panes?
Surface condensation (on the room-side glass) is a humidity and temperature issue that can be managed with ventilation or a warmer glass surface. Condensation between the panes means the sealed unit itself has failed and the glass needs to be replaced.
Can I dry out condensation between the panes?
No. The cavity is sealed and not accessible without replacing the glass unit. Any moisture inside will keep recurring because the seal that is supposed to keep it out has already failed.
Does condensation between panes mean I lost the argon fill too?
Almost always, yes. The same seal failure that lets humid air in also lets the insulating gas fill escape, so the window has lost both its clarity and part of its thermal performance.
